Built for High Capacity Solar Storage and Backup Power
The Avepower 50kWh solar battery is designed for users who need more than a standard residential battery. With a 51.2V nominal voltage and 942Ah nominal capacity, it provides a high-capacity battery storage platform for larger homes, villas, farms, off-grid houses and small commercial sites.
During the day, the battery can store surplus solar power from a compatible hybrid inverter. In the evening, during peak electricity periods or when the grid fails, the stored energy can be used to power essential loads, backup circuits or larger energy systems depending on the project design.
50kWh Class Energy in One Vertical Cabinet
It is a practical choice for projects where the customer wants a large capacity battery in one cabinet instead of installing many smaller battery modules across the site. Avepower can support project based battery configuration, technical matching, and OEM ODM requirements for distributors, installers, and energy storage solution providers.
300A Smart BMS with 2A Active Balancing
The 50kwh solar battery is equipped with a JK 300A smart protection board to manage battery safety, charging, discharging and cell balancing. The BMS helps protect the battery from overcharge, over-discharge, overcurrent and abnormal temperature conditions.
The built-in 2A active balancing function helps improve cell consistency during long-term operation. For a high-capacity battery pack, active balancing is especially important because it can help maintain more stable performance across multiple cell groups and support better usable capacity.
The BMS also supports CAN, RS485 and RS232 communication, allowing the battery to communicate with compatible hybrid inverters and energy management systems.
314Ah LiFePO4 Cells for Stable Energy Storage
This 50kwh solar battery uses CORNEX PF173-314A 314Ah LiFePO4 cells in a 16S3P configuration. LiFePO4 chemistry is widely used in solar battery storage because of its thermal stability, long cycle potential and strong safety performance when combined with a reliable BMS.
The 16S3P structure provides a 51.2V nominal voltage and 942Ah nominal capacity. This makes the battery suitable for 48V-class solar storage systems that require high energy capacity and strong current output.
Bluetooth and WiFi Monitoring for Easier Battery Management
The 50kwh solar battery supports Bluetooth and WiFi monitoring, allowing installers and users to check battery status more conveniently through a compatible monitoring interface. This helps simplify daily operation, system inspection and maintenance.
Through Bluetooth or WiFi monitoring, users can view important battery information such as state of charge, voltage, current, working status, temperature data and alarm status depending on the system configuration. This makes the battery easier to manage without opening the cabinet.
3-Inch Touch Screen Display for Local Battery Status Checking
The 50kwh solar battery is equipped with a 3-inch screen display on the cabinet, allowing users and installers to check basic battery information directly on the unit. This local display is useful during installation, commissioning, routine inspection and after-sales maintenance.
The screen can display key operating information such as battery status, voltage, current, SOC, alarm status and system data depending on the BMS interface. Installers can quickly check whether the battery is operating normally without relying only on external monitoring tools.
CAN RS485 RS232 Communication for Inverter Compatibility
The Avepower 50kWh solar battery supports CAN, RS485 and RS232 communication. These communication options help the battery work with compatible solar inverters, hybrid inverters and energy storage systems.
With proper communication, the inverter can read battery data such as SOC, voltage, current, charge status, discharge status and alarm information. This helps improve charging control, discharge management and system protection. Avepower can help customers confirm inverter protocol matching, battery communication settings and project configuration before shipment.
300A Charge and Discharge Current for High-Power Applications
This 50kwh solar battery supports a standard charge current of 188.4A and a maximum charge current of 300A. It also supports a maximum discharge current of 300A, making it suitable for high-capacity solar storage and backup power systems.
The high current design allows the battery to work with properly configured inverter systems for larger residential and light commercial applications. It is suitable for projects that require stronger DC-side output, longer backup time or higher daily energy use.
Before installation, the inverter model, cable size, breaker configuration, communication protocol, charge voltage and current limit settings should be confirmed by qualified installers.
Expandable up to 16 Units in Parallel
A single Avepower 50kWh class battery can meet many high-capacity residential and small commercial storage needs. For larger projects, the battery supports parallel connection with up to 16 units.
This allows installers and project developers to build scalable battery storage systems for villas, farms, small commercial buildings, telecom backup rooms, off-grid systems and distributed solar storage applications. Using the 50kWh class product positioning, a system with 16 units can reach up to approximately 800kWh class nominal storage capacity.
Vertical Cabinet Design with Practical Installation Hardware
The 50kwh solar battery uses a vertical cabinet design with high-capacity internal battery modules and integrated electrical protection components. It includes a 1P 300A plastic case breaker, 300A square through-type terminal posts and a round 12mm self-resetting switch.
The cabinet also includes 4 M10 lifting holes on the top and bottom and comes with 2 lifting rings for safer handling during installation. With an approximate weight of 364kg, professional lifting equipment and trained installers are recommended.
The 50kwh solar battery cabinet can also be equipped with rollers, making it easier to move and position before final installation. This practical design is suitable for garages, energy storage rooms, utility rooms, villas, farms and light commercial sites.
Whole Home Backup Power for Larger Energy Needs
A 50kWh solar battery is a practical choice for households that want more than basic emergency backup. When connected to a compatible hybrid inverter and solar PV system, the battery can be charged by solar energy during the day. During outages or peak electricity periods, the system can automatically supply stored energy to selected home circuits or the whole home backup panel, depending on the electrical design.
Reliable Performance Across Common Temperature Ranges
The 50kWh solar battery supports charging from 0°C to 55°C and discharging from minus 20°C to 60°C. This operating window allows the system to serve many residential and light commercial environments when installed in a suitable indoor or protected location.
For storage before installation, the recommended storage temperature is 0°C to 45°C for 1 month, 0°C to 35°C for 3 months, and 0°C to 25°C for 6 months.
Customization OEM ODM
Avepower supports OEM ODM customization for this 50kWh solar battery platform. We can help distributors, installers, and project developers customize the appearance, logo, packaging, communication protocol, capacity configuration, and functional options according to market needs.
Whether you need a private label battery product, a specific inverter communication match, or a project based solar storage solution, Avepower can provide engineering support from design to mass production.
Designed for Solar Storage, Backup Power and Off-Grid Systems
The Avepower 50kWh battery storage system is suitable for solar self-consumption, backup power and off-grid energy storage. It can store solar energy during the day and provide power at night, during peak electricity periods or during grid outages.
It is suitable for larger homes, villas, farms, off-grid houses, small workshops, telecom rooms, hybrid inverter systems and small commercial backup projects. For users with higher daily power consumption, this battery offers more stored energy in a single cabinet compared with smaller residential battery models.
